Theoretically it would have been infinitely small. However, once you start looking at more complex theorems, nothing at all may have existed
The letter "e"~13,750,000,000 years agoYes. The big bang brought time and space into existence, therefor is the beginning of time.the letter 'e'
No, the Big Bang was not an explosion in the traditional sense. It was a rapid expansion of space and time that marked the beginning of the universe as we know it.
That depends on what you mean by ripples at the beginning of time. If you are referring to inflation of the universe caused by the Big Bang, and the subsequent "ripples", then those ripples are the leftover, background radiation from the event. If you are referring to ripples in space-time, then it still could have multiple meanings. Space itself can "ripple" in a wave-like fashion when affected by gravity.
Nothing. Unintelligible.
Time doesn't end. It never will. Space and time are woven together to make the 4 diminutional space time fabric that makes up the universe. Space is infinite, therefore, time must be infinite too. In the "beginning" there was no time. It didn't exist yet. In the biggining there was no space as well. It was all contained into and infinitely small and infinitely dense point then the big bang caused the never ending expansion of space AND time.
No. The Big Bang was the origination of the universe; a black hole is the death of a star. Answer The big bang was an explosive expansion of space-time from a singularity, marking the beginning of time and space. Supernovae are exploding giant stars that form (and explode) millions or billions of years after such things as Big Bangs. The Big Bang was not a true explosion, but an enormous expansion. Supernovae are hugely closer akin to explosions.
The big bang marks the beginning of the expansion of space-time from minute to enormous. It marks the beginning of time t = 0. I don't know of any discussion of energy needed for the 'banging' of the big bang. Since it marks the beginning of time it makes no sense for energy to be needed to start the Universe with a bang, for this energy would thus need to be around 'before' the beginning of time. Also, the big bang is technically not an explosion, but an ('explosive') expansion of great great great great great great magnitude. This however does not resolve whether energy need be supplied for a bang or for an expansion. The answer seems to lie in a technicality of time.
When we say about the beginning of time we basically are talking about point Zero, the beginning of everything, the beginning of the universe. When did time begin? It is 13.7 million years ago, which is approx.
At the time universe started: time ZERO, big bang, beginning of the existence of energy and mater.
Yes and no, yes time and space have a beginning and an end, but no because it's infinite and nobody knows about the end yet.
Time, as we understand it, began ticking with the Big Bang approximately 13.8 billion years ago. This event marked the beginning of the universe and the expansion of space-time. Prior to the Big Bang, the concept of time as we know it may not have existed, as time is a dimension that is closely linked to the expansion and evolution of the universe.
The generally accepted theory is that time started with the Big Bang, around 14.5 billion years ago. There are, however, competing theories which suggest that space, time and matter go through cycles or big bangs followed by big crunches (which are big bangs in reverse).
